摘要：
Valve assembly and method in which a valve member is connected to an elongated lever arm for controlling communication between two chambers in an engine. The valve assembly is disposed at least partially within one of the chambers, and the valve member is moved between open and closed by an actuator connected to the lever arm. In some disclosed embodiments, a pilot valve is opened to equalize pressure on both sides of the valve member prior to moving the valve member toward the open position. In others, where a piston in an expansion cylinder is driven by hot, expanding gases from a separate combustion chamber or heat exchanger, the exhaust valve is closed before the piston has completed its exhaust stroke, and pressure is allowed to build up in the expansion cylinder to a level corresponding to the pressure in the combustion chamber before the valve member is moved toward the open position.
摘要（中）：
阀组件和方法，其中阀构件连接到细长的杠杆臂以控制发动机中的两个室之间的连通。 阀组件至少部分地设置在一个室内，并且阀构件通过连接到杠杆臂的致动器在打开和关闭之间移动。 在一些公开的实施例中，在将阀构件移动到打开位置之前，先导阀被打开以均衡阀构件的两侧上的压力。 在另一些情况下，膨胀气缸中的活塞由来自单独的燃烧室或热交换器的热膨胀气体驱动时，排气阀在活塞完成排气冲程之前关闭，并且允许压力在膨胀 在阀构件朝向打开位置移动之前，气缸达到对应于燃烧室中的压力的水平。
